Hey Ibritz
Lisa has already done an excellent job of giving you a very detailed response. So I will just add a few things here.
First of all...this is good that you are on the right path towards figuring out what is causing your mystery symptoms. It can be frustrating to be in this limbo land where you are not sure of what you will end up being diagnosed with. I can tell that you are well prepared for this visit already with your list of symptoms and medications. That is going to be very helpful to the doctor. You want to tell him or her about the intensity and duration of these symptoms. I would also tell your doctor that you are concerned it may be Multiple Sclerosis.
The first questions that come to mind to ask your doc for such a visit are:
* Which possible diagnoses will you investigate? When I went into my doctor for the first time with my list of symptoms I asked him point blank...what sorts of things will you be looking for?
* What tests will you need to do to find out what this is?
* What are the similarities between fibromyalgia and Multiple Sclerosis symptoms?
* What can I do in the meantime to deal with these particular symptoms?
I am guessing that if there is any suspicion of MS...that she will order an MRI for you.
Try not to be scared or alarmed at this point...I know easier said than done. You seem to be proceeding in a very logical way. You do not know that this is MS...it may very well not be. The best thing you can do at this point is to gather facts...and your doctor is going to know the best way to proceed. Only concentrate on what is pertinent at this point and that is to begin the process of elimination of possible diagnoses.
When you are at the beginning of things...and this may be a long road...I think it is best for one's sanity to only focus on what is right before you...and in this case it is fact gathering...writing down the symptoms to take to your doctor and then allowing him or her to do the necessary tests to get to the bottom of things. There are many things which could be causing your symptoms and to worry about them all will make you go crazy. Believe me...I know this from experience.
I wish you the best of luck. Please do come back to tell us what happens for your first visit. I will be thinking of you.
